MAPPING OF RADIONUCLIDE CONTAMINATION IN RUSSIA

摘要

Compilation and publication in 1998 of the "Atlas of radioactive Contamination of the European part of Russia, Belarus and Ukraine" is the main result of developing a new scientific branch of subject cartography - radioactive contamination mapping. The maps of ~(137)Cs terrain contamination were published repeatedly after the Chernobyl accident with the storage of new information. The Atlas shows a complete data collection on the radioactive contamination, and it is based on the theoretical background of spatial providing of this original information. An important feature of radionuclide mapping is the unity of principles of compiling information on the contamination, based on combination of the airborne-gamma-spectrum survey data, and laboratory methods of the soil samples analyses. Another considerable feature of the Atlas maps is the use of a differential approach to the ways of computer mapping of different parts of the contaminated areas depending on their contamination levels, relief, extent of forest cover and ploughing.
